The Extra Light Front hub from Alchemy Bicycle Works may not be the lightest availabe hub option, but considering its superior design and construction, it does allow for the best possible performance in a front wheel. The ELF is able to achieve this through several innovations and features.
Most significantly is its use of a 6900 series bearing in place of the common 6800 series found in most front hubs. The 6900's important difference lies in the thicker cross section and use of larger balls than traditional 6800 series bearings. The consequence of the stouter bearing is an increased load capacity.
The E.L.F's hub flanges are angled at 6 degrees with a flange width of 82mm, allowing for a stiffer and stronger build. In hub flanges, wider is better for strength, with a slight aerodynamic sacrifice. To further increase wheel strength, the 6900 bearings are spaced further out than in traditional hub designs. Alchemy sites this design as virtually eliminating axle bowing and flex by reducing the the dropout to bearing distance 8-13mm compared to common designs. The resulting performance characteristics are increased bearing life and increased lateral stiffness of the wheel.
